The present invention relates to railway rolling stock. and more particularly to a novel locomctivebody construction.

The primary object of the present invention is toprovide a locomotive body, formed of sheet metal. with the parts thereof arranged to provide a box construction and integrally united, as by welding, to provide for strength and durability.

More particularly, the body is provided with reinforcing walls'are themselves reinforced bytransverse or horizontal reinforcing walls and these horizontal reinforcing walls provide a support for cylinders of a Diesel engine, thus adaptor: the pt locomotive body for the reception of a combined steam and Diesel engine power plant. 'In order to cool the cylinder walls of the e the horizontal reinforcing walls are formed 05 box construction providing water chan- 9 pets ugh which water may be circulated to thecylinder With the above and other objects in view the invention cots in matters more particularly 5 com 4 w s: wings, in which Mg. is a iental vertical section;

Like characters of reference are employed toghout to design t corresponding parts. Th of the present locomotive'is concted with a cab i at the extreme rear end 5 thereof, and extending in a forward direction minted out hereinafter with reference to the ac-' en on the line from the cab is a housing that is divided into two compartments 2 and 3, the compartment 2 being located directly in front of the cab i and the compartment 8 being at the extreme for ward end of the locomotive body. The floor of- 5 the cab i comprises two, vertically spaced, horizontal plates 4 and 5, the lower plate 5 being provided with a bearing 8 adapted for the reception of a king pin on a wheeled truck. The cab construction is more clearly shown in Figs. 1 and 5 10 wherein it is readily apparent that the two 'fl00i' plates 4 and 5 are integrally united with the vertical side walls 1, which are also integrally united with the roof I. The two floor plates 4 and 3 are spaced rigidly apart by transverse reinforcing walls'S which divide the space therebetween lntotanksFThe rear end of the cab I is closed by a rear wall iii, integrally united with the other walls and plates of the cab, and at its @rward end by a bulkhead H which divides the go cab from the compartment 2, the bulkhead ii motive body, the portions of the side walls which relate to the cab being designated l, the portions relating to the compartment 2' being designated to and the portions which relate to the forward so compartment 3 being designated lb. The two side wall portions in, in front-of the cab I, are termed with substantially horizontal portions extending inwardly with respect to the compartment 2, each horizontal portion being disposed at the top of its respective wall la. The inwardly extending portions are designated l2 and-may be seen more clearly'ln Fig. 6. The walls 62 are welded to a boiler it as designated at l3 and thus become an integral part of the boiler. The side 40 is la and the horizontal walls 62 are reinforced by transverse walls or webs it, the walls or webs it being located on opposite sides of the compartment 2 in pairs. Transverse reinforcemerits. it extend across the top of the compartnt 2. The portions or members 88 which unite the walls or webs is are integrally united, by welding, to a wall ll of the boiler ll. The transverse webs 95 are formed at ii for the reception of bearings for supporting a crankshaft of a: Diesel engine, the bearings being shown at is in Fig. 8 as supporting the crankshaft 28 .of a Diesel engine. v

The floor oi the compartment 2 is formed 01 two vertically spaced horizontal plates 2i and 22, 6d

22, and the vertical walls 23 being welded to the web extensions 24. As may be seen in Figs. 2 and 6, the extensions 24 on the walls or webs l5 divide the space between the floor plates 2| and 22 into a plurality of tanks.

In order to enclose the bearings l9 and the crankshaft 20, and yet to permit access thereto when such is desired, removable cover plates are provided. For the purpose of supporting the plates 25 the side walls la are provided with flanges 25 and the vertical walls 23 with flanges 21. No securing means has been illustrated as holding the plates 25 in place but it will be understood that any suitable type of fastening elements may be employed. Spaced in a vertical plane above the floor plate 2| are horizontal walls 28 of box construction, the walls 28 being disposed between pairs of webs l5 and welded thereto for the purpose of rigidifying the same. As may be seen'in Fig. 8, the horizontal walls 28 constitute shelves for the support of cylinder walls 29 of a Diesel engine and, being hollow, provide means for conveying cooling liquid to the cylinder walls.

The compartment 3 is provided with a floor formed of vertically spaced plates Ill and 3|, supporting a bearing 32 for the reception of a king gpin on a wheeled truck, the plates and 3| being transversely reinforced by walls forming water tanks 25a. Welded to the upper plate 5. are vertical walls 33 that are joined to the side walls 1b by horizontally extending portions 34 to provide water tanks 35 which communicate through openings 38 with the water tanks 35a. A continuous channel 36 extends from the tanks formed between the floor plates 4 and 5 of the cab and the water tanks 3511 thus provided between the floor'plates 30 and. ll of the compartment 3, the channel 38 being separated from the tanks 31 formed between the floor plates 2| and 22 of the compartment 2. The tanks 31 are provided for the reception of fuel oil.

The locomotive body thus formed is of comparatively light weight, inasmuch as it avoids the use of heavy castings and forgings, and the manher in which the body is fabricated of sheet metal shapes welded together with the various necessary accessories, such as water and fuel oil tanks, built into the body provides for strength and durability and results in a locomotive wherein the power plant may be'located between the forward and rear trucks and wherein the entire weight, including the liquid weight, is equally divided between the forward and rear trucks.

Although a specific embodiment of the invention has been illustrated and described it will be understood that various changes may be made boiler, said side walls having laterally diverging portions and downwardly extending portions spaced laterallyfrom the side edges of said floor structure and terminating in the horizontal plane of said floor'structure, webs integrally united with said floor structure and extending laterally therefrom, said webs having upwardly extending portions integrally united with said side walls and transverse portions integrally united with saidboiler, and removable walls secured to bottom edges of said side walls and to adjacent edges 0 said floor structure.
